1. Please specify termination and packaging codes:
MSS1246T-105KLD
Termination:L=RoHS compliant matte tin over
nickel over phos bronze.
Special order:
T = RoHS tin-silver-copper
(95.5/4/0.5) or S = non-RoHS
tin-lead (63/37).
Packaging:C
=7″ machine-ready reel. EIA-481
embossed plastic tape (200 parts
per full reel).
B=Less than full reel. In tape, but not
machine ready.
To have a leader and trailer
added ($25 charge), use code
letter C instead.
D=13″ machine-ready reel. EIA-481
embossed plastic tape (800 parts
per full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc
using a Coilcraft SMD­‑A fixture in an Agilent/
HP 4263B LCR meter or equivalent.
3. DCR measured on a micro-ohmmeter and a
Coilcraft CCF858 test fixture.
4. SRF measured using an Agilent/HP 8753D
network analyzer and a Coilcraft SMD­‑D test
fixture.
5. DC current at which the inductance drops the
specified amount from its value without current.
6. Current that causes the specified temperature rise
from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount
Components” before soldering.
